Please Buy The Fastest Class A Motorhome on Earth

There’s something deeply satisfying about the idea of taking a motorhome from coast to coast. If there was ever a rolling domicile ready to take on the challenge of making that journey as fast as possible, it would be MoHo. This big block-powered 1977 GMC is currently the fastest Class A motorhome in the world, and now it can be yours thanks to Facebook Marketplace.

The Marketplace listing states this high-speed motorhome build was originally sponsored by Hot Wheels and its parent company Mattel in an effort to promote awareness about Charcot-Marie-Tooth disorder, a degenerative nerve disease. Not a show vehicle by any means, “MoHo” is currently the world’s fastest Class A motorhome with a certified top speed of 121.50 MPH, which was achieved out on the Bonneville Salt Flats.

At the heart of this Class A beast sits a 502 cubic-inch RamJet Chevy V-8 engine, which comes bolstered by modern fuel injection, a Magnaflow exhaust system, and a 125 shot of nitrous. The listing notes that the big block is capable of laying down 700 horsepower at 6000 RPM. To make the most of that power, the motorhome has been extensively modified from nose to tail. The floors, walls and ceiling have all been skinned in aluminum, while the exterior panels have been smoother for improved aerodynamics. A full chromoly roll cage extends the entire length of the vehicle, while a collapsible steering column and onboard fire suppression bring added peace of mind. Brakes and suspension components have been upgraded with a variety of GM-sourced parts, while a Ridetech air ride up front keeps things comfortable at speed. The rear end features a taller 3.07 gear set for top speed runs, helped along by a custom aero package.
